Multiwall polycarbonate 10 mm is a durable, UV-protected roofing material designed to provide even, glare-free daylight for your garden structures. The opal finish softens harsh sun rays, making it a comfortable choice for spaces where you want brightness without the intensity of direct heat.
These double-walled panels are engineered for strength, featuring a 1700 g/m² mass that stands up to the elements while remaining lightweight enough for straightforward installation. Whether you are covering a patio or upgrading a greenhouse, this sheet offers a reliable, long-lasting solution for your roof.

Why Choose This Opal Finish
The opal tint is specifically crafted to manage solar radiation. By diffusing incoming light, it prevents the “hot-house” effect often found under clear panels, keeping your terrace or pergola significantly more comfortable during peak sun hours.
This material is a practical choice for warm climates where heat management is a priority. It protects both people and plants from excessive glare while maintaining a bright, inviting atmosphere for your outdoor living space.
Installation and Compatibility
These sheets are designed for versatile use across various roof structures, including carports and walkways. For projects requiring different light levels, you might consider the 10 mm Bronze sheet for increased shading or a 6 mm clear sheet for maximum light transmission. Always remember to seal the open ends of the channels with appropriate tape to maintain the integrity of the panels over time.

- Internal Structure The internal design (channels shape) of the sheets may vary based on stock levels, but the technical specs are identical. We never mix different structures in the same order to ensure a uniform look.
- UV Protection & Installation Polycarbonate sheets must be installed with the UV-protected side facing up (facing the outside) for the protection to work. The UV side is clearly marked on the protective film.
- Handle with Care Handle the sheets carefully to prevent scratches and damage.
- Storage Store in a cool, dry place away from direct sunlight.
Use cases and compatibility
This 10 mm thickness is excellent for patio roofs, pergolas, and greenhouses where you need a balance of structural rigidity and effective light diffusion for comfort.
Choose thinner 6 mm clear sheets for lighter projects, or opt for 16 mm bronze variants if your structure requires superior thermal insulation.
Ensure your rafter spacing is compatible with the 10 mm panel width and always protect the open ends of the sheet channels with professional sealing tapes.
